I've started rotating with Enochian and B4 and F4, there was 62 HQ gear selling on the market for next to nothing so I updated everything apart from necklace (those were quite expensive and the difference was negligable) - so she's now got all 62 gear and is up to 630ish Spell Speed. Before today I never really noticed it being quicker with upgrades, but today I can really feel the difference. It feels less sluggish, and also considering i'm DPS, i'd consider Spell Speed to be of paramount importance to providing DPS. It's a bit like people not understanding in games like Borderlands that reload speed is also DPS related, if you understand what I mean. I just didn't know what was best. I haven't melded materia into the new gear yet, but I will do tomorrow.
